Resolves #55755
@inqueue noticed an issue with what shows up in the Logstash Overview Events Emitted chart versus what shows in the Logstash Pipelines Listing Events Emitted listing.
In the overview chart, you can see the total events emitted are ~77k.
In the listing page, if you sum the events emitted, it's only ~6k
After some digging (and help from @ycombinator), we discovered a couple of things:
ephemeral_idandhashvalues we needed to calculate the right metricsThis PR addresses that by ensuring we execute the same kind of query so we get the same results. We are able to do that by, instead of sending a single query to fetch all pipeline metrics, we send individual ones (in parallel) for each known pipeline.
Now, we see:
It's a little complicated with logstash monitoring documents, due to the nested fields, so you'll notice some of that in the code.
